Officers say credit card skimming devices were placed on gas pumps throughout Calgary in at least 38 different gas stations.

Police investigating reports of the devices searched two homes Wednesday and uncovered what they are describing as a credit card and identification counterfeiting lab, along with $150,000 worth of high-end clothing and merchandise.

"This included hand tools and paint to create overlays, pinpad keys, cash, a track two data reader and encoder, and samples of fraudulent credit cards and counterfeit identification," police said in a press release.
